Answer:

4 5/8 the answer you have is correct :)

Step-by-step explanation:

First, you want to make the mixed fraction into an improper fraction.

 7 x 4 + 3 = 31 (31/4)

3 x 8 + 1 = 25 (25/8)

Now you want them both to have a common denominator.

31/4 x 2/2 = 62/8

Now you are ready to subtract!

62/8 - 25/8 = 37/8

Finally, convert 37/8 to a proper fraction.

37/8 = 4 5/8

Answer:

G

Step-by-step explanation:

In the equation, 8.5 will represent how much money Oscar earns per hour, and the x represents how many hours he works. The inequality sign shows that the sum of 8.5x and 100 has to be at least 397.50 (397.50 and up), so H and J are automatically wrong. If Oscar had given his brother 100 dollars, there would be a subtraction sign, but there is an addition sign instead, meaning he gained 100 dollars that did not come from his job. It would be the most logical to say that his brother had given it to him, so G is the correct answer.

Answer:

Radius of cylinder = 4.5 inch

Circumference of Base = 9π inch

Area of base = 20.25π

Step-by-step explanation:

Given:

Diameter of cylinder = 9 inch

Height of cylinder = 22 inch

Find:

Radius of cylinder

Circumference of Base

Area of base

Computation:

Radius of cylinder = Diameter of cylinder / 2

Radius of cylinder = 9 / 2

Radius of cylinder = 4.5 inch

Circumference of Base = 2πr

Circumference of Base = 2π(4.5)

Circumference of Base = 9π inch

Area of base = πr²

Area of base = π(4.5)²

Area of base = 20.25π

Step-by-step explanation:

the punctuation was a little confusing, but heres what i think u meant

"A grocery store is giving a reusable bag to every person who donates more then than 5.00 to charity, Courtney donates 1.25, will she get a bag?"

for this answer we see that x is the amount of money someone donates, so x has to be greater then 5.00, so the mathematical expression would be shown like this

x > 5.00

if x is not greater then 5.00 (like if its equal or less) then the store will not give a new bag, in this case 1.25 is not an amount that x can be

The true statement is B.

The function will have at least one zero on the interval -5 < x < 4

Here we have a polynomial function g(x), and we know that it passes through two known points (-5, 6) and (4, -3).

Remember that a relation is only a function if each point on its domain is mapped into a single point in the range.

Also, this is a polynomial function, so it is continuous, then there are no jumps.

So, at some point in that interval x ∈ (-5, 4), we must have a zero for our function, where a zero is a value of x such that:

g(x)=  0

Then the correct statement is B, g(x) has at least one zero i the given interval.

A triangle has three sides, the first, second, and the add up to 24, since that's the perimeter

The second side = the first (let's call it L) + 2

The third is two more then the second, so L + 2 + 2

first side = L

second = L + 2

third = L + 2 + 2

add all three together, L + L + 2 + L + 2 + 2 = 24

combine the L's and 2's

3L + 6 = 24

subtract 6 from both sides

3L = 18

divide by 3

L=6

so the first side is 6, the second is 8, the third is 10

The length of the missing side is √69

The triangle is a right triangle with the following parameters

Hypotenuse = 13

Leg = 10

Represent the missing side with x

By the Pythagoras theorem, we have

x = √Hypotenuse² - Leg²

This gives

x = √13² - 10²

Evaluate

x = √69

Hence, the length of the missing side is √69

The correct answer is that the data set {3, 7, 4} is represented in the given histogram.(option-a)

The given histogram represents the number of children in each age group who need to travel to school. Since the histogram has only three bars, we can conclude that there are only three age groups.

The first bar represents children aged 5-10, of which there are 3. The second bar represents children aged 11-13, of which there are 7. The third bar represents children aged 14-18, of which there are 4.

Therefore, the data set that is represented in the histogram is:

{3, 7, 4}

None of the other data sets given match the values in the histogram. The first data set has duplicate values and is not sorted by age group. The second data set includes ages that are not represented in the histogram. The third data set has values for ages 6, 11, 12, 13, 14, 15, 17, and 18, but the histogram does not have bars for all those ages. (option-a)

The degree solutions of the equation are 51.82 degrees and 128.17 degrees

From the question, we have the following parameters that can be used in our computation:

cos² (x) + cos (x) − 1 = 0

Let y = cos(x)

So, we have

y² + y - 1 = 0

When solved graphically, we have

y = ±0.618

This means that

cos(x) = ±0.618

Take the arccos of both sides

x = cos-1(±0.618)

Evaluate

x = 51.82 degrees and 128.17 degrees

Hence, the angles are 51.82 degrees and 128.17 degrees

Step-by-step explanation:

Well let’s make a fraction 2/40.

So we have to simplify it to 1/20.

And we do 1 / 20.

So 1 / 20 is .05.

To make this a percent we put the seminal place 2 places to the right.

So the percent is 5%.

Answer:

To find the unknown value in the proportion (2x + 1) / 2 = (x + 2) / 5, we can cross-multiply the terms on the left-hand side and the right-hand side to eliminate the fractions. This gives us the equation 2(2x + 1) = 5(x + 2), which simplifies to 4x + 2 = 5x + 10. Subtracting 4x from both sides of the equation, we get 2 = x + 10, which can be rewritten as x = -8. Therefore, the unknown value in the proportion is x = -8.

Answer:

The answer is "(0.73,0.87)".

Step-by-step explanation:

Given:

number of girls\(= 64\)

number of boys\(= 16\)

Total number of children\(= 64+16= 80\)

So,\(n=80\)

Calculating the value of the proportion which is given by girls:

\(\hat{p}= \frac{\text{number of girls}}{\text{total number of childrens}}\)

  \(=\frac{64}{80}\\\\=\frac{8}{10}\\\\= 0.8\)

Therefore the confidence interval is:  

\(\to \hat{p}\pm z_{(1-\frac{\alpha }{2})}\sqrt{\frac{\hat{p}(1-\hat{p})}{n}}\\\\\to 0.8 \pm 1.75\sqrt{\frac{0.8(1-0.8)}{80}}\\\\\to 0.8 \pm 1.75 \sqrt{\frac{0.8(0.2)}{80}}\\\\\to 0.8 \pm 1.75 \sqrt{\frac{0.16}{80}}\\\\\to 0.8 \pm 1.75 \sqrt{0.002}\\\\\to 0.8 \pm 1.75 (0.04)\\\\\to 0.8 \pm 0.07\\\\\to (0.73,0.87)\)

\(\therefore \\\\\text{The lower confidence limit} = 0.73\\\\\text{The upper confidence limit} = 0.87\\\)
